Abstract
The Infrared Cloud Imager (ICI) is a ground-based infrared thermal imaging system used to identify and classify clouds based on the downwelling atmospheric radiance in the 8-14 μm wavelength region. Data obtained during a deployment in Barrow, Alaska during February - May 2002 has been combined with radiosonde and microwave radiometer data to calculate spatial cloud statistics for the months of March and April 2002. The results show a general trend of increasing cloudiness during this period, and a short transition time between clear and cloudy skies. A comparison of cloud statistics computed from the full ICI images with statistics computed from a single ICI pixel suggest that a point sensor would underestimate cloudiness during this data period.
